These notches are arranged to register in alignment with one another to form an elongated contiguous U-groove into which the projecting rib 25 enters when the press portion 23 is depressed so as to lift the lock prong 22 of the tumbler 21 apart from the lock groove 18 of the plunger 15.
- the discs 27, 28 and 29 are formed integrally with rotary shafts 30, 31 and 32 respectively at one end thereof.
- the rotary shafts 30, 31 and 32 are reduced in length progressively in this order and each extend horizontally outwardly of the casing 19 in a direction opposite to the opening 20 for the plunger 15.
- the shafts 30, 31 and 32 are concentrically mounted in superposed relation to one another, the intermediate shaft 31 being rotatably mounted on the inner long shaft 30 and the outer short shaft 32 rotatably mounted on the intermediate shaft 31.
- the shafts 30, 31 and 32 disposed outside of the casing 19 are attached to and frictionally driven by dials 33, 34 and 35, respectively, in a manner hereafter to be described.
- the casing 19 is provided internally with a radially projecting longitudinal rib 36 at least at one location, the rib 36 having a length sufficient to span over the juxtaposed discs 27, 28 and 29 combined as shown in FIG. 2.
- the discs 27, 28 and 29 each are provided peripherally with a plurality of equally spaced grooves 27b, 28b and 29b, respectively, which are engageable with the rib 36 selectively by operation of either of the dials 33, 34 and 35.
- axial slits 27c-29c each interposed between and slightly above adjacent grooves 27b-29b as exemplarily shown with respect to the disc 29 in FIG. 6, in which only the slits 29c are revealed to allow the solid peripheral surface portions 29d overlying the respective slits to elastically deform upon pressure engagement with the rib 36.
- a similar frictional drive means is embodied in the rotation of shafts 30, 31 and 32 as illustrated in FIGS. 3, 4 and 5, respectively.
- the shafts 30, 31 and 32 each are provided peripherally with a plurality of equally spaced grooves 30a-32a which are selectively engageable with radial ribs 33a, 34a and 35a formed on the inner peripheral walls of the dials 33, 34 and 35, respectively.
- axial slits 33b, 34b and 35b underlying the ribs 33a, 34a and 35a, respectively, which slits allow their respective associated ribs to elastically deform or flex inward upon moving contact with the solid peripheral surface portions 30b-32b between adjacent grooves 30a-32a of the respective shafts 30-32.
- Each of the dials 33, 34 and 35 is provided at its outer periphery with indicia such as numerals which correspond in number to the grooves 30a (31a, 32a). There are a total of eight such grooves in each of the shafts 30, 31 and 32 and hence there are eight digits on each of the dials 33, 34 and 35 which are equally spaced apart in registry with the positions of the grooves 30a-32a in the respective shafts 30-32.
- the lock assembly 10 is locked and unlocked as follows.
- the pair of slider pull tabs 11 and 12 are oriented to confront side by side, when the plunger 15 is inserted into the casing 19 with the prong 22 arrested in the lock groove 18 as shown in FIG. 2.
- the male and female parts 13 and 14 remain locked if at least one of the notches 27a, 28a and 29a of the respective discs 27, 28 and 29 is displaced or held out of alignment with the rib 25 of the tumbler 21 by rotating the corresponding one of the dials 33, 34 and 35.
- the lock assembly 10 is unlocked by making inching rotation of all or any of the dials 33, 34 and 35 so as to bring all of the disc notches 27a, 28a and 29a into alignment or registry with the tumbler rib 25, whereupon the press portion 23 is depressed against the tension of the lug 26 to permit entry of the rib 25 into the aligned notches 27a, 28a and 29a and departure of the prong 22 from the lock groove 18 of the plunger 15 which is then ready to be pulled out from the casing 19.
- a lock assembly 10 shown in FIG. 7 is similar in all structural details to the lock assembly 10 already described with reference to FIGS. 1-6, except for the construction of a tumbler 21.
- This tumbler 21 has an annular chamber 21a communicating with the opening 20 for receiving the plunger 15.
- a prong 22 extends upwardly from the lower portion of the tumbler 21 and is adapted to engage in the lock groove 18.
- a spring 26 is interposed between the lower inner surface of the casing 19 and the prong 22 and normally biases the tumbler 21 upwardly so that the press portion 23 is exposed above the casing 19 and the rib 25 is lifted apart from the notches 27a, 28a and 29a.
- FIGS. 8-12 inclusive there is shown another modified form of lock assembly 100 which comprises a male part 130 having a drum-like body 131 and a female part 140 substantially in the form of a cylindrical casing 190.
- the male part 130 has a plunger 150 extending horizontally inward from one side of the drum-like body 131.
- the plunger 150 has a head 160 substantially in the form of a truncated cone defining a beveled guide surface 170.
- a lock groove 180 is formed in the upper peripheral portion of the plunger 150 for receiving a lock tumbler 210.
- the female part 140 comprises a drive disc 270 and a driven disc 280 both rotatably supported within the casing 190.
- the drive disc 270 has an integral hub 400 concentric therewith which extends outwardly of the casing 190 and which is internally threaded for threaded engagement with a bolt 300 extending from a dial knob 330 through an axial bore 330a formed therein.
- the driven disc 280 has a horizontally projecting eccentric pin 410 movable in an annular groove 420 formed in the rear surface of the drive disc 270 and engageable with a drive pin 410' projecting from the drive disc 270 into the annular groove 420.
- the driven disc 280 is thus connected to and driven by the drive disc 270.
- Designated at 290 is a retaining washer interposed between the drive disc 270 and the dial knob 330 and adapted to hermetically seal the junction therebetween.
- the discs 270 and 280 have radial notches 270a and 280a respectively, which are brought into and out of alignment with each other by rotating the dial 330.
- the discs 270 and 280 have axial slits 270b and 280b, respectively, formed in their lower portions diametrically opposed to the notches 270a and 280a, the slits 270b and 280b serving to enable the discs 270 and 280 to be assembled with the casing 190 with a resilient tight fit.
- the lock tumbler 210 is pivotally mounted in the casing 190 through an elongated slot 210a in which is received a pivotal pin 210b extending perpendicular to the plane of the female part 140.
- the slot 210a is vertically elongated so as to allow the tumbler 210 to move substantially linearly vertically in addition to pivotal movement.
- the tumbler 210 generally in the form of a latch plate has a lock prong 220 including an arcuate cam surface 220a and engageable in the lock groove 180, a tongue 250 at an end remote from the prong 220 and an upwardly projecting lug 230 adjacently above the prong 220.
- a wire spring 260 has a coil portion 260a overlying the elongate slot 210a and a first arm portion 260b elastically borne against the upper inner wall of the female part 140 and a second arm portion 260c elastically supported on the lug 230 of the tumbler 210, the arrangement being that the lock prong 220 of the tumbler 210 is normally biased clockwise to retain locked relation with the plunger 150.
- Designated at 430 is a retaining rib axially extending from the lower portion of the male part 13 diametrically opposed to the lock groove 180 of the plunger 150 and adapted to engage in a packet 440 formed in the lower portion of the female part 140 to retain the male part 130 in place when coupled with the female part 140.
- the lock assembly 100 can be locked and unlocked with ease.
- the plunger 150 can be inserted into the casing 190, in which instance with advancement of the plunger 150 its beveled guide surface 170 is brought into sliding contact with the cam surface 220a of the tumbler 210, causing the latter to move substantially linearly upward against the tension of the spring 260.
- the tumbler 210 returns to its original position under tension of the spring 260 with the lock prong 220 fully received in the lock groove 180, thereby completing a true lock of the assembly 100.
- the dial know 330 may be simply turned in either direction.
- the dial 330 When unlocking the assembly 100 or separating the male part 130 from the female part 140, the dial 330 is turned to match a selected combination of numerals thereon so as to bring the disc notches 270a and 280a into registry to allow entry therein of the tumbler tongue 250 as shown in FIG. 9.
- the plunger 150 is then pulled out, when the tumbler 210 rotates about the pin 210 counterclockwise until the lock prong 220 is lifted apart from the lock groove 180.
- the drive disc 270 and the driven disc 280 may be made unitary to simplify the construction and operation of the lock assembly 100.
